Yeah. I wasn't disparaging the "plastic thingies"
only commenting on the power of a primer.
The "plastic thingies" are fun & a good excercise for "drying firing" in that you'll actually be punching holes too. Do hang a blanket in back of your target as they will bounce right the hell off of hard walls & dent regular drywall even after going thru cardboard.
Too, your plastic bullets will shoot quite a bit lower than normal rounds as there's no recoil to bring the pistol into proper line of sight when fired. (Let's see who bites on that last comment)
